/ˌɔːnᵻˈθjʊərɪk/, U.S.

/ˌɔrnəˈθ(j)ʊrɪk/

Origin: A borrowing from German, combined with an English element. Etymons: German Ornithursäure , -ic suffix.

Etymology: < German ornithur- (in Ornithursäure ornithuric acid (M. Jaffe 1877, in Berichte der Deutsch. Chem. Ges. 10 1925) < ornitho- ornitho- comb. form + ur- (in Urin urine n.¹) + Säure acid) + -ic suffix.

Biochemistry.

ornithuric acid n. a colourless crystalline acid isolated from the excreta of birds whose food contained benzoic acid; 1,4-dibenzoylornithine, C₁₉H₂₀N₂O₄.

1878 Harper's Mag. Apr. 793/1 No hippuric acid is formed by birds, the benzoic acid forming a new conjugated acid which he calls ornithuric acid.

1911 Science 22 Dec. 887/2 Quite probably the benzoate would give rise to ornithuric acid, since it is known that this acid is formed when benzoate is excreted through the kidneys of birds.

1953 Science 1 Jan. 593/2 The following chemicals are wanted by the Registry of Rare Chemicals..amygdalin; delta-tocopherol; ornithuric acid; protoanemonin.

1980 Ann. Rev. Ecol. & Systematics 11 277 Excretion of ornithuric acid from the cecum by red grouse..is probably the result of detoxification of prolignin and other polyphenols.
